SwathPro
• The SwathPro system is a technology that
prevents overlap.
SwathPro Capabilities:
• Minimize Overlap
• Minimize Skip
SwathPro
Minimize Overlap
• Why overlap should be minimized?
• Ex. If your spraying Velpar on an alfalfa field
for weeds you don’t want to overlap because
Velpar can kill alfalfa if over applied.
SwathPro
Minimize Skip
• Why skips should be minimized?
• Ex. If your doing a burn-down you don’t want
to leave skips because you want everything
dead.
